The listing, Single Bow Stud Earrings - 5 pcs has ended.
These are all single earrings, small. There is one silver tone, one navy, one light blue, one pink, and one teal. If you have several holes in your ears, they would look cute even though they dont match in color. Or they could be used in a craft project as well! They are painted metal and are probably vintage, though no idea from when.
